The Glaucus

[Gianteye]

Hi, folks. I just finished the latest Super-Releaser design. It's a soft robotic quadruped called the Glaucus, and I urge you to give it a look. This post has links to where you can download the design, read a tutorial on how to make your own, and lots more.

Good afternoon Gianteye, I have tried looking around online for a fluid control (specifically, the pneumatic system) that you guys use for the Glaucus. Since then I've been trying to make my own pneumatic system. I have ran into a problem where I'm not sure if i should make a pneumatic system that works such that:

The left hole on the luer seat increases with air, then decreases;
and then the right hole increases, then decreases.
OR
The left hole increases, the decreases while the right hole is increasing;
and then the right hole decreases while the left hole increases again.

I'm skeptical that the first idea will not even make the Glaucus walk forward. Will both ideas work? Or did you guys try something else that is better? Any help would be appreciated guys! Thank you!

Thanks for the question kevin29292.

The Glaucus controls function as a fade between the two channels, and rely on an intentional constant bleed on the system. One of the factors behind this choice is that when you partially inflate the Glaucus, its legs bend down and grip the surface better, which helps it move a bit more with every step.

Hope this is helpful!

Thanks for the info! Very interesting stuff.
